                   eGenix.com pyOpenSSL Distribution


             An easy-to-install and easy-to-use distribution
             of the pyOpenSSL Python interface for OpenSSL -
            available for Windows, Mac OS X and Unix platforms

This announcement is also available on our web-site for online reading:


The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python.

It comes with an easy-to-use installer that includes the most recent
OpenSSL library versions in pre-compiled form, making your application
independent of OS provided OpenSSL libraries:


pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS-
aware network applications as well as certificate management tools:


OpenSSL is an open-source implementation of the SSL/TLS protocol:



This new release of the eGenix.com pyOpenSSL Distribution updates the
included OpenSSL version to the latest OpenSSL 1.0.1h version and adds
a few more context options:

New in OpenSSL

 * Updated included OpenSSL libraries from OpenSSL 1.0.1h to 1.0.1i.
   See https://www.openssl.org/news/secadv_20140806.txt for a complete
   list of changes. Most fixes apply to the OpenSSL DTLS implementation,
   which pyOpenSSL currently does not support. The following fix is
   relevant for pyOpenSSL applications:

   - CVE-2014-3511: A flaw in the OpenSSL TLS server code allows a
     man-in-the-middle attacker to force a downgrade to TLS 1.0.

New in pyOpenSSL

 * Compiled pyOpenSSL with OPENSSL_LOAD_CONF to have the OpenSSL
   libs automatically load the openssl.cnf configuration file. This
   allows easy configuration of additional OpenSSL parameters and
   defaults, locations of certificate files, hardware engines, etc.
   without having to change the application code. Please see the
   documentation for details.

 * Updated the included CA root certificate bundles to Mozilla's
   2014-07-15 update.

pyOpenSSL / OpenSSL Binaries Included

In addition to providing sources, we make binaries available that
include both pyOpenSSL and the necessary OpenSSL libraries for all
supported platforms: Windows x86 and x64, Linux x86 and x64, Mac OS X
PPC, x86 and x64.

We've also added egg-file distribution versions of our eGenix.com
pyOpenSSL Distribution for Windows, Linux and Mac OS X to the
available download options. These make setups using e.g. zc.buildout
and other egg-file based installers a lot easier.


The download archives and instructions for installing the package can
be found at:



Before installing this version of pyOpenSSL, please make sure that
you uninstall any previously installed pyOpenSSL version. Otherwise,
you could end up not using the included OpenSSL libs.


Commercial support for these packages is available from eGenix.com.

for details about our support offerings.
